1 AG? 754, Specification of Letters Application filed June 20,

To all whom it may concern:

Be it known that I, Ennnnr A. Jonas a citizen of the United States, and residing at Danville, Pittsylvania County, State of Virginia, have invented certain new and useful Improvements in Spinning Machines, of which the following is a specification.

This invention relates to mechanism by which yarn is laid and wound upon a rotating bobbin or yarn receiver. It has particu lar reference to the mechanism which builds a small body of yarn at the lower portion l ot' the bobbin or spindle called the bunch diiiierent elements enter and then builds ainain body of yarn on the spindle. The necessity for building the bunch is well known in the art since it acts through the automatic teeler of certain inachines to prevent winding off all of the yarn on the bobbin which would cause a defect in the fabric and produce what is called a second. Much difficulty has been experienced in producing a machine which will build. an entirely satisfactory bunch and a satisfactory main winding, and this seems to have been due to the fact that so many into consideration. The yarn constituting the bunch is not drawn oif in use but goes to waste and there fore fromv the standpoint of economy it is essential that the amount of yarn used in the bunch be reduced to a .niinimun'i. It is essential, however, that the bunch have a certain thickness in order to operate the tceler. it is also essential' that the bunch he so wound as to firm and toy prevent tangling or breaking of the yarn, and it is desirable that it shall be placed low on the spindle or bobbin so as to permit as much yarn as possible to be placed on the spindle by the main winding. bunch. as well pends largely upon the length of the traverse or strokes of the builder arm during its -formation and upon the gain of the traverse or the pick at each stroke of the builder. I have found that in building ashort, thick and liriu bunch and then the main winding it is necessary that the traverse and the pick orgain shall be considerably less in building the bunch than in the main Winding, but that the gain or pick in building the main winding should not be as much greater than the pick or gain in tormingthe bunch as is the traverse or strokes of the builder arm The character of the as of the main winding, de-

in building the main Winding greater than the traverse or stroke in building the bunch. in other words, the increase in the gain or pick must not correspond to the increase in the stroke or traverse inchanging from the bunch to the main winding. If the increase in the pick corresponds to the increase in the stroke or traverse it will follow either that the traverse in forming the hunch is too long to form a short or satisfactory bunch or, the gain in the main winding will be too great, and the result will be that the yarn will be spread out too thin in the main winding and the not be produced.

The present invention is designed to cause the building or" the bunch at as low a point as desired, a thick, as firm and asshort as desired, preventing while avoiding waste and then automatically causingthe building-of a main winding with a predetermined traverse and a predetermined pick or gain to give to the main winding the desired thickness and taper.

Home of the features of this invention reating to the pick mechanism are disclosed but not claimed in my prior Patent Number 1206 54 2 November 28; 1916, where the proper main winding will claims related particularly to the 1necha-,-

nisin there disclosed for changing the travin forming the bunch. Thebroader :as relating to this matter may; therefore, be said in a sense to be divided out of my patent although the present construction includes improvements on those ideas. present invention also includes improve ments on the traverse controlling mechanism ot my prior patent. The novel features of the invention will be apparent from be following description taken in connection a with the drawings;

My invention is applicable to spinning machines of well known types and while it is not necessary to go into a detailed'explanation of those machines in order to enable one skilled in the art to understand the invention it is necessaryto have in mind certain well known features of those machines. As shown in Figure 1 the machine in which the invention is applied embodies a main frame construction 10 and a cross frame 11 carrying a series of ordinary rotating spindles or bobbins 12 in the usual manner. A ringrail 13 is adapted to reciprocate up and down the bobbins in order to guide the yarn properlyin winding and this ring rail is given its up and down movement by-the push rod 14 sliding through the bearings 15, 16 on the parts of the main frame. The lower end of the puslrrod lirests on the horizontal arm of the bell crank lever 17 which is pivoted at 18 in a frain 19 secured to a fixed part of the machine. The vertical arm of the lever 17 is connectedto a cable 20 which is constantly pulled towards the left in Figure 1 by any well known means such as a rollerand weight.

The tendency of the bell crank lever 17 under the influence of the cable 20 is therefore to raise the ring rail and the tendency of the ring rail is to descend by gravity except when pushed up by the push rod. The amount which the ring rail will be raised is limited by mechanism including the pivoted segment 21 to which the cable 20 is secured and a chain 22 which passes over the roller secured to a fixed partof the frame and down to the builder arm 24-. The builder arm is pivoted at one end to a fixed partof the frame and the pull on the chain 22 through the cable 20 tends to raise that builder arm but it is held down by the contact of a roller carried by it with the operating Quill. The main clam which engages and holds down the builder arm, as is customary in machines of this kind, is shown at 25 mounted on the end of the rotating shaft 26 which is turned by any suitable means such as the pulleys 27. A roller 28 in fixed position on the side of the builder arm engages the periphery of this cam and the rotation of the cam therefore makes the builder arm oscillate vertically thus pulling on the chain 22 and turning the bell crank 17 to lower the ring rail 13. The extent of the reciprocation or traverse is controlled by' the shape of the cam 25. In addition to the above mentioned features the builder arm is also provided with mechanism for causing the lever 17 to turn on its pivot gradually and progressively raising the ring rail 13 along the spindle without changing or effecting the traverse or length of stroke of the ring rail. This is done by the pick mechanism including a ratchet wheel 29 and a pawl 30. The ratchet wheel is secured to the end of a rotary shaft 31 mounted in bearings 82, 33 on. the builder arm and carrying the worm gear 34. A segmental sliding plate 35 havingteeth 36 on its edge engaging the worm gear 34 is moved by the rotation of I the shaft 31. The plate 35 carries a roller 25? over which the chain 22 passes after it leaves the roller 23. The end of the chain 22 is secured at a fixed point 38 to the builder arm so that a movement of the sliding plate 35*with its roller 37 to the right as shown in Figure 6 will have the practical effect of: lengthening the chain connection 22 between the segment 21 and the builder arm thus permitting the bell crank lever 17 to turn to the left raising the ring rail. The particular construction by which the pawl and ratchet pick mechanism rotate the shaft 31 and cause the elevation or gain in the trans verse will be described in detail later and it is sufficient now to'say that it isoperated by the reciprocation of the builder arm and this broadly considered was all old in the art. I I

According to my present invention 1' makeuse of a supplemental or bunch cam 39 in addition to the usual cam 25 and mount it on the same shaft 26 with the main cam. I

also mount 011 the builder arm 24. a supplemental roller 48 to cooperate with the sup plement'al cam 39 in building the bunch.

ing the building of the bunch. The two arms 25 and 29 are so arranged that when the roller 48 is in operative position they will alternately engage their rollers at each revolution of the cam shaft the high points of each cam only engaging its roller. This action will be apparent from the diagranr matic illust ation in Figure 9 from which it will be seen that as the roller 28 rides over the high parts of the cam 25 it will lift the roller 48 out of contact with the supplemental cam 39 and conversely when the high parts or the supplemental cant 39 engage the roller 48 the roller 28 will be lifted out of F or instance, starting with the roller 48 in contact with the supplemental car n39 at a withthe cam moving in the direction indicated by the arrow, the roller will ride over the surface of cam 39 to the point marked 3) lifting the roller 28 out of contact with the main cam at c and allowing it to come in contact with the main cam again at (Z. The roller by its contact with the main cam will then lift the roller 48 out of contact with the supplemental cam ride over the surface of the main cum to the point marked 6. At that point the roller 48 will again come in contact with the supple" mental cam 89 at f andthe operation will thus continue around the periphery or the cams, the builder arm being depressed alter nately by the high portions of the two cams; This results in shortemngthe upward movement oi"- the builder arinwhich it would normally have under the influence of the mains cam 25 only and multiplies the number of reciprocatlons of the bullder arm and consequently ofthe ring rail during each revolution of the cam shaft; This gives a short substantially uniformtraverse during the building 01" the bunch and the connections through the chain 22may be so adjusted that when the roller 28 at thebeginning of the operation .is at the highest point of the cam 25 the ring rail will be at the bottom of the spindle 12 or at the point'wher'e it' is de sired to commence building the bunch. The

ring rail will rise from that point the'defi nite amount above indicated as the points of the cams engage the rollers thus producing the short traverse for the bunch The roller 48 is held in stationary position on the builder arm'throughout the building of the bunch and is then automatically rendered inoperative so asto throwout of operation the supplemental cam 39 and permit the main winding to proceed underthe influence oi the main cam 25 alone.

erse of the ring rail;

The mechanism for causing a gain of the 39 and the' roller 28 will The roller 28' will then follow the surface of the main cam both. in the low parts and in the high traverse as above indicated includes the rotary shaft 31 mounted on the builder arm and carrying the worm gear 34 which 1l1$l1ES with teeth in the sliding segmental plate 35. The shaft- 31 is given a slight rotary movement at each reciprocation of the builder arm and thus the plate 35 is given a slight and rotatively mounted on the-shaftBl. This pawl 30 has below its pivot a sharp pointed end 5lwhich is adapted to engage the teeth of the ratchet wheel, and the pawl has an outwardly extending straight projection52, the weight of which tends to keepthe point 51 in contact with the ratchet teeth. It will be understood that the pawl will ride freely over the teeth when moved in a counterclockwise-direction, as shown in Figure 2,. The' plate hason lts pr0 ect1on end dia ranu matically oppositethe pawl a weigl it 53 which normally tends to turn the plate 50 so as'to move the pawl counterclockwise to its upper position. Secured to a fixed poris a stop 54 inthe path ofthe tion of the-mainframe of the inachinethere proj eating end 52 of the pawl so that as the builder arnr is elevated-in its stroke the end 52 of the pawl will be engaged by the stop oand the plate.50 will thereby be swung around on its pivot on the shaft 31 and the ratchet whee sponding to the amount of upward movement of the builder arm after the point 52' 29 will beturned an" amount corree v strikes the stop.- In order to-be'able to regu- 2 late the time in the upward movement oi the builder'arm when the pawl engages the stop a plate 55 is rctatively mounted on the shaft '31'closeagainst the plate 50 and it carries a projecting pin 56which is adapted to make contact with the side 'o'lthe builder arm at a certain point in its rotary movement on the'shat't. This plate 5M3 secured to the platenoO by an adjust-ablebolt 57 or other suitable'means passing through'the slot 58. The relation ofthe plates 50 and 55" -may therefore be changed and they may be" secured together in the positiondeslred. In

this way when the stop 56 strikes the side of the builder arm it limits the upwardmove 'ment or the pawl 30 and by controlling its position. determines at what point in the up ward movement of the builder arm it will come into operation by contact with the stop 54-. In building the bunch the parts may be so set asto make the pawl engage the ratchet wheel during a suflicient amount of the upward stroke to cause the particular amount of gain or pick necessary informing the bunch. The stroke of the builder arm in building the hunch is comparatively short and consequently the normal gain would be comparatively small but as above stated it may be regulated and thus I am enabled to build a short, thick, bunch with a slight gain at each stroke at thebottom of the spindle.

When the supplemental cam 39 is thrown out of operation at the endyol the building of the bunch and when the builder arm thereupon commences to make the long stroke. for the main winding the result would naturally follow that the long stroke atter the pawl 2 comes in contact with the stop 54: would cause a correspondingly greater turning movement for the ratchet wheel 29 and its shaft 31 and consequently a correspondingly greater gain in the traverse. Such a correspondingly great er gain, however, j would make the conical layers of yarn on the spindle spread out too much thus not making a winding oli the proper thickness and taper. According to my invention, therefore, I-have provided mechanism for interfering with or cutting in two the normal action of the pick mechanism when the change ismade from the bunch winding to the main winding. This includes mechanism connected with the supplemental roller a8 and which is brought into operation when the roller l8 is disabled F or thrown out of operationv at the building thelbunch.

As shown particularly in Figure 4;, the roller l8 torithe supplemental cam is carend of ried. by a bell crank lever,59 pivoted at 60 to a member 61 securedon top of the builder arm 24 by the bolts 62. In building the bunch the bell crank lever 59 and itsroller a8 are held in the position shown in Figure 4; by a latch or pivotedlocl: 63 mounted on the pivot 64. secured to the builder arm. One. arm ot the bell crank leverrests on one end of this latch 63 whereas the other end or the latch 63 hasprojectingfrom it a pin 65 which as seen in Figure 6 rides in a slot 66 in the sliding plate 35. The engagement of the pin 65 with the slot holds thelatch 63 111 position and therefore holds the roller &8 in operative position. When, howev r the pick mechanism ;has moved the plate 35 a suflicient distance in causing the gain of thetraverse the plate will finally pass beyondthe point where the pin 65 can engage the slot and thereupon the latch 63 will be free to turn on its pivot (a. The weight of the mechanism bearing on the rollere8 willthen suddenly turn .the latch 63 and also the bell crank lever throwing the roller 48 out of operation.

Inlhe construction shown particularly in Figures 4: and T I have illustrated a pivoted stop or blockot metal 6? pivoted at 68 to the builder arm near its end and near the ratchet wheel QQ'and pick mechanism. That pivoted stop is connected by an adjustable link mechanism (39 to one arm otthe bell crank lever 59 so that when the bell crank lever is turned to lower the roller 48 out of operative position it at the same time turns the stop 67 into vertical position. lVhen in vertical position the lower end of the stop 67 is above the pin 56 which, as heretofore explained, controls the amount of free movement 01' the pawl 30 around the ratchet wheel 29. i The effect of interposing this stop 67 in the path of the movement of the pin 56 is therefore to cut short the picking action of the pawl and to delay the time in the upward movement of the builder arm when the pawl 30 comes in contact with the stop 54:. cally cuts in two the normal pick and prevents the amount or" gain from increasing in the same proportion that the strokes]? the builder arm has increased. In the subsequent operation of the device in building the mainwinding the stop 67 remains in position in the path ofthe pin 56, thus continuously interfering with or cutting in two the pick. This construction enables me to. so regulate the gain in the traverse in forming the main winding as to produce the best form of winding and permits me to use a different pick in the bunch winding; so as to get the best form 01' winding for t ie purpose of'the bunch. It furthermore permits: me to start theibunch at the bottom without, making the gain unduly long on This automatithe main 'windingsince' l can make the nckmgactron commence at any period of, the upward stroke ofthe builder arm de- I sired. t will be observed that the pin 65 is adjustable in the slot 70 so as to regufl 7 chines but can be applied with little trouble orexpense to manymachines now in gen eral use. .It' will be observed that the builder arm 2% is ,pivotally mounted at T1 to a fixed part of the frame and oscillates in a vertical plane from that pivot under the influence of the pull exercised by the chaiuQZ and the action of the cams'28 andAS. The action of the apparatus in building a bunch with a uniform movement to the builder arm and a short-substantially uniform traverse a small gain results in causing the rail to dwell longer at the bottom of the quill during the formation ofthe bunch and thus. gives the operator time within which to piece up broken ends before going on the regular-or long stroke.

lVhile I have illustrated preferred cmbodiment of my invention it will be understood that it is not limited to that partic ular formsince various changes may be made in the construction without departing from its principles.
